Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for multi-cell positioning. In example embodiments, a method is provided. The method includes transmitting, from a first network device, a first reference signal to a terminal device served by a second network device. The method further includes receiving a second reference signal from the second network device. The method further includes determining a first time difference between a time at which the first RS is transmitted and a time at which the second reference signal is received. In addition, the method includes transmitting information on the first time difference to a location server. As such, the location server can determine positioning information about the terminal device.

Abstract: Example embodiments relate to wideband communications based on availability assessment. A method for communication comprises performing availability assessment on a set of configured frequency subbands to obtain an availability result, the availability result indicating that at least one of the set of configured frequency subbands is available for a period of time for transmission of intended information and transmitting supplementary information that has been prepared using the at least one frequency subband during a first portion of time within the period of time. The method also comprises preparing the intended information based on the availability result and transmitting the prepared intended information using the at least one frequency subband during a second portion of time following the first portion of time within the period of time. As such, the processing of the intended information can be adapted depending on the dynamic available subband (s) indicated by the availability result.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for downlink control of unlicensed sub-bands. The method comprises determining a search space configuration associated with control resources on a plurality of sub-bands which are unlicensed, the search space configuration indicating candidates for detection of downlink control information for the plurality of sub-bands; determining, from the search space configuration, positions of the candidates on the control resources within each of the plurality of sub-bands; mapping an available number of candidates to the determined positions based on a transmission bandwidth assumed by a terminal device; and transmitting downlink control information to the terminal device on the mapped candidates.
